TL;DR: Balanced partitioning of stem length into upper and lower internodes and internode maximum specific weight are important in genotypic accumulation and mobilization of stem reserves in wheat.
Abstract: Wheat crops grown in dryland areas may depend more on stem reserves for grain filling than on current photosynthesis. We evaluated the hypothesis that internode length, weight, and specific weight of genotypes affect accumulation and mobilization of stem reserves. This knowledge might complement selection in stressful environments. Genotypic variation for internode characteristics and their effects on dry matter accumulation and mobilization were measured at 10-d intervals in 11 diverse wheat cultivars grown under well-watered and droughted field conditions across 2 yr. Relationships among internode characteristics and accumulation and mobilization of stem reserves were determined. The main effect of year, irrigation, genotype, and harvest date and genotype x harvest date interaction were significant. Internode length, weight, and specific weight were reduced under drought. Mobilized dry matter from peduncle, penultimate, and the lower internodes ranged from 43 to 171, 81 to 272, and from 198 to 474 mg, respectively. Mobilized dry matter was less in well-watered than in droughted conditions for peduncle (93 vs. 110 mg) but not for penultimate (173 vs. 143 mg) and the lower internodes (331 vs. 304 mg). Drought increased mobilization efficiency, expressed as percentage of maximum dry mater mobilized, in the peduncle, penultimate, and the lower internodes by 65, 11, and 5%, respectively. Stem maximum specific weight was correlated (r = 0.64) with stem mobilized dry matter. Balanced partitioning of stem length into upper and lower internodes and internode maximum specific weight are important in genotypic accumulation and mobilization of stem reserves in wheat.

TL;DR: It is suggested that there is neural disruption in the superior cerebellar peduncle in patients with schizophrenia, which may be involved in the cognitive abnormalities found in schizophrenia.
Abstract: Disconnection in the frontal-thalamic-cerebellar circuit is thought to be associated with cognitive abnormality in patients with schizophrenia. The superior cerebellar peduncle is involved in neural connectivity in the circuit. Because diffusion tensor imaging (DTI) can detect neural disconnection, we investigated whether there was neural disruption in the superior cerebellar peduncle in patients with schizophrenia. DTI was performed in 21 schizophrenic subjects and 21 age- and sex-matched healthy subjects. Cognitive cluster scores were attained by using the Positive and Negative Syndrome Scale (PANSS). Schizophrenic subjects had significantly lower fractional anisotropy (FA) in the right and left superior cerebellar peduncles than healthy subjects. Higher FA in the left superior cerebellar peduncle was associated with worse cognitive function in patients with schizophrenia. These findings suggest that there is neural disruption in the superior cerebellar peduncle in patients with schizophrenia, which may be involved in the cognitive abnormalities found in schizophrenia.

TL;DR: The valuable variation existing among wild accessions can be exploited following introgression with cultivated lentils, which will help in the flow of useful genes from wild to cultivated lentil for generating wide spectrum of variability and its subsequent use in genetic restructuring of lentil.
Abstract: Exploitation of wild gene pool for breeding is a common practice in an increasing number of cultivated plants. The cultivated lentil could not attain the substantial improvement in the yield potential due to loss of genes for higher productivity and lack of resistance against biotic and abiotic stresses. The absence of evaluation data of wild lentils for characters of economic importance, besides biotic and abiotic stresses, is one of the constraints in their use in lentil breeding programme. In the present study, 70 wild accessions from four wild Lens subsp./sp. (L. culinaris subsp. orientalis, L. odomensis, L. ervoides and L. nigricans) along with 3 checks (Precoz, PL-406 and PL-639) were evaluated for phenological and agro-morphological characters, for their reaction to three fungal diseases (wilt, powdery mildew and rust) and screened for tolerance to moisture stress. The wild accessions showed higher performance for branches/plant as compared to cultivated genotypes. Similarly, a few accessions of L. culinaris subsp. orientalis were earlier to flower and had higher seeds and seed yield/plant as compared to cultivated lentil. However, some were comparable with cultivated genotypes for flowers/peduncle, peduncle length and plant height. The mean performance for flowers per peduncle, leaflets per leaf, plant height, seeds and seed yield per plant increased, while decreased for days to flowering and maturity, and branches per plant during the evolution of cultivated lentil from the wild Lens taxa. Of Lens taxa, L. nigricans had the maximum resistant accessions for biotic and tolerance to abiotic stresses. The valuable variation existing among wild accessions can be exploited following introgression with cultivated lentils. It will help in the flow of useful genes from wild to cultivated lentil for generating wide spectrum of variability and its subsequent use in genetic restructuring of lentil.

TL;DR: CFRs, evoked by periorbital stimulation and recorded from the cerebellar cortex, could be inhibited by stimulation of two distinct mesencephalic areas and it was concluded that stimulation of the ventral area activated nucleo-olivary fibres.
Abstract: Stimulation around the superior cerebellar peduncle or within the deep cerebellar nuclei is known to inhibit the inferior olive with a very long latency. It has been suggested that this inhibition is mediated by the GABA-ergic nucleo-olivary pathway, but alternative explanations such as activation of an indirect excitatory pathway or a pathway via the red nucleus are possible. A long-latency inhibition via the nucleo-olivary pathway would have profound implications for cerebellar function and the present study was performed to test alternative explanations and to characterize the nucleo-olivary inhibition. Climbing fibre responses (CFRs), evoked by periorbital stimulation and recorded from the cerebellar cortex, could be inhibited by stimulation of two distinct mesencephalic areas. One was located within the superior cerebellar peduncle and the other about 1 mm further ventrally. Inhibition evoked from either area occurred in the inferior olive and was independent of a red nucleus relay. Single Purkinje cell recordings revealed that inhibition from the ventral area was not secondary to olivary activation. It is concluded that stimulation of the ventral area activated nucleo-olivary fibres. The inhibition elicited by stimulation within the peduncle probably resulted from indirect activation on the nucleo-olivary fibres via antidromic activation of the interpositus nucleus. The time courses of the inhibition from the two areas were indistinguishable. The duration of the strongest inhibition was short and had a sharp peak at about 30 ms. It is suggested that the time course of the inhibition is important for temporal regulation of learned responses.

TL;DR: Through the genetic merit prediction of three parents, it was found that the additive and additiveadditive epistatic effects of C.carpio var.Wuyuanensis could decease the body weight, total length and standard length in progenies.
Abstract: Red common carp are very excellent genetics and breeding materials in aquaculture in China,but the study on their quantitative genetics has not been conducted yet.In this paper,the additivedominanceepistasis genetic model was used to analyzed additive,dominance and epistatic genetic effects for body weight and 10 morphometric traits(total length,standard length,body depth,body width,head length,snout length,eye diameter,iterorbital width,Caudal peduncle length and Caudal peduncle depth) from three variants of red common carp,Cyprinus carpio var.Singuonensis,C.carpio var.Wuyuanensis and C.carpio var.Color,based on F_(2) data from diallel cross experiment.The results indicated: except the trait of body depth,the additive additive epistatic effects were observed in the other traits.In which,the additiveadditive epistatic effects were significant in traits of body weight,total length,standard length,head length,snout length and caudal peduncle length.The proportions of epistasis to phenotype variance of 10 traits were: body weight 11.4%,total length 22.6%,standard length 14.0%,body width 8.3%,head length 24.2%,snout length 17.5%,eye diameter 12.9%,interorbital width 23.1%,caudal peduncle length 5.4% and caudal peduncle depth 20.1%.Through the genetic merit prediction of three parents,it was found that the additive and additiveadditive epistatic effects of C.carpio var.Color could increase the body weight,total length and standard length in progenies,but the these two effects of C.carpio var.Singuonensis and C.carpio var.Wuyuanensis could decease the body weight,total length and standard length in progenies.Epistatic genetic effect could play an important role in genetic selection and breeding in fish.
